Understanding Stockfish's evaluation

[programarivm]

Stockfish's evaluation function assigns a numerical score to each position. A human-readable version of it should also be implemented to easily understand which side has an advantage.

Range	Evaluation	Symbol
-0.26 to 0.26	The position is equal	=
0.27 to 0.7	White has a slight advantage	⩲
0.7 to 1.5	White has a moderate advantage	±
> 1.5	White has a decisive advantage	+ −
-0.27 to -0.7	Black has a slight advantage	⩱
-0.7 to -1.5	Black has a moderate advantage	∓
> -1.5	Black has a decisive advantage	− +

Happy coding!
